| 摘 要： | 通过对铅及其氢化物的理化性质，铅矿床矿流体包裹体气液相成分、内生锡矿物的化学成分、铅矿物的共伴生矿物特征等相关问题的研究，认为铅氢化物，铅合金氢化物是铅成矿的主要迁移形式。在强还原、富氢、高压环境下，可随岩浆、热液、热气迁移至地壳浅部。在减压，贫氢，富硫的相对氧化环境；硫化成铅的硫化矿物及其硫盐矿物，或在氢逃逸氧化的贫硫环境；形成铅的单质及铅的合金矿物，并在长期地质事件中叠加，富集成铅矿床。

| Abstract: | According to the research into physical-chemical quality of Pb and its hydrogen compound, gas-liquid composition of fluid inclusion in the mineral of Pb deposit, chemical composition of innate Pb mineral and characteristics of paragenetic mineral with Pb mineral, the hydrogen compounds of Pb and Pb alioy are considered to be the main removing forms in Pb metallogenesis. Under the conditions of strong reduction, rich in hydrogen and high pressure. They can remove to the upper part of the crust following the magma, thermal liquid-gas and form Pb sulfide-sulfate minerals in the oxidation environment of P-decrease, H-poor and S-rich or minerals of Pb and Pb alloy in the H-excape and S-poor environment, which become the Pb deposit by superimposition and enichment in the geological activity of a long period. |
